" Seattle does not have bad neighborhoods; it has a handful of problematic blocks scattered throughout the city. What distinguishes those problematic blocks from the rest of the city? A jumble of factors, acting in combination. Hot spots are more likely to be on arterial roads, more likely to have vacant lots, more likely to have bus stops, more likely to have residents who don’t vote, more likely to be near a public facility such as a school.
